按报道的描述，应该是外星科技：
Ascending Technologies Jan Stumpf and Michael Achtelik monitored a Pelican quadrocopter modified to receive power from several laser pointers focused on a photovoltaic cell mounted on the airframe. The internal battery was then charged using power generated by the photovoltaic cell.

注意红字部分：用几个激光笔聚焦在一个太阳能电池上，能产生出足够的功率驱动四轴之余还给电池充电？
现在的电机撑死做到10g/W的能效比，即使这样一台500g的四轴也至少需要50W悬停功率，能输出50W功率的太阳能电池板就远不止500g了吧？
